Furnas is one of the most extraordinary destinations in the Azores and one of the few places in Europe where you can soak in naturally heated volcanic thermal pools, watch geothermal steam vents hissing from the ground, and eat a stew that was slow-cooked underground in volcanic soil. The Furnas Azores hot springs experience is genuinely unlike anything you will find elsewhere in Portugal, and this guide covers everything you need to plan your visit, from what to expect at Parque Terra Nostra to practical tips on timing, transport, and food.
What Is Furnas and Why Is It So Unique?
Furnas is a small village on the eastern side of Sao Miguel island in the Azores, Portugal. What makes it extraordinary is its geothermal activity. Furnas sits within a volcanic caldera and is one of the most geothermally active areas in Europe.
The comparison that comes up most often is Iceland or the geothermal fields of New Zealand’s Rotorua. Hot springs, steam vents, bubbling mud pools, and sulfurous fissures emerge from the earth throughout the village and surrounding valley. The ground beneath Furnas is essentially alive.
For travelers visiting the Azores, Furnas is one of the unmissable highlights of Sao Miguel. The combination of thermal bathing, volcanic geology, botanical gardens, and traditional underground cooking creates an experience that concentrates several extraordinary things into a single day trip.
Furnas Valley: The Volcanic Crater
The Furnas Valley is technically a massive volcanic crater, or caldera, formed by the collapse of a magma chamber following ancient volcanic eruptions. The surrounding hills and the lake visible from the miradouros on the approach to Furnas are part of this caldera structure.
Lake Furnas sits within the caldera and is one of the most scenic viewpoints on the approach road. The Miradouro do Pico do Ferras offers a panoramic view of the lake and the full sweep of the Furnas Valley before you descend into the village. This viewpoint is worth a stop before continuing to the village itself.
The last volcanic eruption in the Furnas Valley occurred in 1630, creating a small island in Lake Furnas. The geothermal activity today, while dramatic in appearance, represents the tail end of this volcanic system rather than active eruption risk. The area is continuously monitored by volcanic scientists.
Parque Terra Nostra: Thermal Pools and Botanical Gardens
Parque Terra Nostra is the centerpiece attraction in Furnas and the main reason most visitors make the journey from Ponta Delgada. It combines one of the most impressive thermal bathing experiences in Portugal with extensive tropical botanical gardens.
The Thermal Pool
The star feature is the large outdoor thermal pool, naturally heated by geothermal water drawn directly from volcanic sources beneath the park. The water is iron-rich, which gives it a distinctive orange-brown color. The temperature is warm and consistent, similar to a comfortable bath.
The pool is large enough that it rarely feels overcrowded, even on busy days. It is shallow throughout, which makes it accessible for all ages. The iron content in the water is said to have therapeutic properties, though the primary appeal is simply the extraordinary experience of bathing in naturally volcanic water.
Note that the iron-rich water will stain light-colored swimwear. Wear an older swimsuit or one you do not mind discoloring.
The Botanical Gardens
The botanical gardens surrounding the thermal pool are extensive and beautifully maintained. The Azores’ mild, humid climate allows an extraordinary range of tropical and subtropical plants to thrive. The gardens contain tree ferns, cycads, bamboo groves, collections of hydrangeas in multiple colors, ginkgo biloba avenues, water lily ponds, and dozens of species not commonly found in mainland European gardens.
Walking the garden paths before taking to the pool is the recommended approach. Allow 45 to 60 minutes for the gardens depending on your pace. The combination of tropical vegetation with steam rising from thermal streams running through the park creates an atmosphere that feels genuinely otherworldly.
Pricing and Practical Information
Entry to Parque Terra Nostra, including the botanical gardens and the thermal pool, costs 16 euros per adult. Children and seniors receive discounted entry.
There is a hotel attached to the park, Terra Nostra Garden Hotel, and guests staying at the hotel can use the thermal pool and the natural jacuzzis in the evening after the park closes to day visitors. If you want the pool essentially to yourself in a peaceful setting, an overnight stay at the hotel provides that experience.
If you plan to dine at the park’s restaurant, guests eating there receive free entry to the botanical gardens. This is worth knowing if you want to combine lunch with a garden visit without paying the full entry.
Dedicated changing rooms with lockers are available. Arrive at opening time to have the pool at its quietest.
The Free Public furnas azores hot springs and Steam Vents
One of the best things about Furnas is that some of its most dramatic geothermal features are completely free to visit. In the center of Furnas village, a public park contains a remarkable concentration of hot springs, boiling mud pools, and sulfurous steam vents that emerge directly from the ground.
The water temperature in these springs exceeds 100 degrees Celsius. The vents release constant plumes of steam into the air. The smell of sulfur is noticeable but not overwhelming. Walking among these features on the boardwalk paths that thread through the park gives a visceral sense of the geothermal energy beneath the surface.
This public area is accessible throughout the day at no charge. It is also the location where the famous underground-cooked stew, cozido, is prepared each morning. Large metal pots are lowered into the ground near the hottest vents and left to slow-cook in the volcanic heat for several hours before being served in the village restaurants at dinner.
The public hot springs area is a shorter and less manicured experience than Parque Terra Nostra, but the geological drama is arguably more intense. Both are worth visiting.
Cozido das Furnas: The Underground-Cooked Stew
Cozido das Furnas is the traditional dish of Furnas and one of the most unique food experiences in the Azores. It is a slow-cooked stew containing multiple cuts of pork and beef, blood sausage, chourico, and vegetables including potatoes, cabbage, and carrots.
What makes it extraordinary is how it is cooked. Large pots are placed in holes dug next to the geothermal vents in the public park area each morning and left to cook slowly in the volcanic heat for six to eight hours before service.
Most restaurants in Furnas offer cozido at dinner, typically from 6.30 pm onward. Booking ahead is advisable in summer and on weekends as the dish is popular with both tourists and locals making the trip specifically for it.
Honest assessment: the dish is a cultural and geological novelty that is absolutely worth trying, but it is a simple, rustic stew rather than a refined dining experience. The flavor is mild rather than complex. The vegetables and meats are tender from the long cooking time. Think of it as a hearty winter stew cooked by a volcano rather than a culinary revelation.
Caldeiras Restaurant and Tony’s Restaurant are among the most established options in the village for cozido. Prices are reasonable, typically 14 to 18 euros per person for the stew and a drink.
Other Things to Do in and Around Furnas
Miradouro do Pico do Ferras
The viewpoint above Furnas on the road from Ponta Delgada offers arguably the best elevated view of Lake Furnas and the caldera valley. Stop here on the way into Furnas rather than after, when afternoon cloud often builds over the mountains.
Lake Furnas
Lake Furnas is a volcanic crater lake surrounded by forested hills and accessible from several points around its perimeter. Birdwatching around the lake margins is rewarding. The lakeside village of Furnas provides access to the water’s edge and reflection views of the surrounding landscape.
Poça da Dona Beija Hot Springs
Poça da Dona Beija is a set of smaller, more intimate thermal pools on the edge of the village, open primarily in the evening from around 2 pm onward. Entry costs around 8 euros, roughly half the Parque Terra Nostra price. The pools here are smaller and more natural-looking than the main Parque Terra Nostra pool, and the evening atmosphere with illuminated pools and steam rising into the dark is particularly atmospheric.
For visitors who want a second thermal experience beyond Parque Terra Nostra, or for those on a tighter budget, Poça da Dona Beija is the best alternative.
Furnas Church
The Church of Our Lady of Remedies in Furnas village dates from the 18th century and provides a picturesque focal point in the village center. The surrounding village streets are pleasant to walk through, with traditional Azorean architecture and gardens.
How to Get to Furnas from Ponta Delgada
By Hire Car
Hiring a car is the most practical and flexible way to visit Furnas. The drive from Ponta Delgada takes approximately 40 to 50 minutes depending on the route. The EN1 via Ribeira Grande is the main road, while the more scenic southern route via Agua de Pau passes through interesting landscape.
Having a car means you can stop at viewpoints like Miradouro do Pico do Ferras on the way in, control your arrival time to beat the tour groups, and combine Furnas with other nearby attractions on the same day.
By Organized Tour
Numerous organized tours depart daily from Ponta Delgada and typically combine Furnas with other eastern Sao Miguel attractions. Tours usually include transport, entry to Parque Terra Nostra, and sometimes lunch. They are convenient but limit your flexibility and typically mean arriving at the same time as several other groups.
By Public Bus
Buses connect Ponta Delgada to Furnas but services are limited and the journey takes longer than driving. Check the current Azores Bus timetable before relying on this option, particularly for return journeys in the evening.
Best Time to Visit Furnas
Time of Day
Arrive at Parque Terra Nostra at opening time, typically 10 am, to have the thermal pool at its least crowded and the gardens in their best morning light. By midday, tour groups arrive and the pool fills up significantly. The free public hot springs can be visited at any time, but morning light is also preferable for photography.
Season
Sao Miguel is a year-round destination. Summer brings the highest visitor numbers and the best guaranteed weather. Spring and autumn offer excellent conditions with smaller crowds. Winter visits are possible and relatively mild but involve more unpredictable weather.
The thermal pools are enjoyable in any weather, and the botanical gardens are arguably at their most atmospheric in soft light or light mist. Furnas receives more cloud and rainfall than the coast, so an overcast day in Ponta Delgada does not necessarily mean a poor experience in the valley.
Where to Stay Near Furnas
Terra Nostra Garden Hotel
Staying at Terra Nostra Garden Hotel provides after-hours access to the thermal pool when the park is closed to day visitors. The hotel is set within the botanical gardens themselves, making the morning walk to the pool a genuinely special experience. It is a mid to upper range property priced accordingly.
Guesthouses in Furnas Village
Several guesthouses operate within Furnas village at more budget-friendly prices. Staying in the village means you can access the hot springs in the early morning or evening when day-trippers have left, which transforms the experience.
Ponta Delgada as a Base
Most visitors stay in Ponta Delgada and make Furnas a day trip. This works well with a hire car. Ponta Delgada has the widest range of accommodation and restaurant options on the island.
Practical Tips for Visiting Furnas Hot Springs
- Wear an older swimsuit to the thermal pool. The iron-rich water stains light-colored fabric.
